I've pushed an updated patch to "wip-gcc7" based on the latest
'core-updates'.
The cross-compiler toolchain is still broken: it fails to build the very
last GCC. For armhf, the build system tries to include
"gnu/stubs-soft.h" during "./configure" and fails, even though it gets
"--with-float=hard" as a flag.
When building the AArch64 cross-compiler, GCC segfaults later in the
process:
build/genmatch --gimple ../../gcc-7.4.0/gcc/match.pd > tmp-gimple-match.c
/gnu/store/vfqvdfdnd8fi9gcx710mpfaf0x4dfd37-bash-minimal-5.0/bin/bash: line 1:
1789 Segmentation fault
